An inner rod of the ejector rod 5 can slide in an outer tube and be fixed, the lead screw is fixed to the inner rod, the length of the ejector rod can be adjusted by rotating the lead screw, and the ejector rod is made to fix the push device with certain pressure.
Description
Technical field
The invention belongs to coal mine gas extraction technical field, relate to a kind of pressure break pipe pusher of essential safe type.
Background technology
Coal mine gas extraction is the important process ensureing Safety of Coal Mine Production and resources effective utilization, and pressure break is one of important technical improving gas pumping rate.In fracture job, by the restriction of work-yard, can not use main equipment that pressure break pipe is sent in tens meters of dark pressure break holes, scene generally all uses manpower to push, waste time and energy, because the thrust of people is limited, pressure break pipe can not be sent in darker hole, limit the application of fracturing technique.
Summary of the invention
The object of the invention is to enter boring for pushing pressure break pipe, there is provided one can utilize underground coal mine high-pressure air source, structure is simple, the pressure break pipe pusher of easy for installation, essential safety, carry out alternative manpower, faster pressure break pipe can be sent in deep hole, raise the efficiency, save manpower, reduce the device of labour intensity.
For achieving the above object, the present invention adopts following structural design scheme.As accompanying drawing 1.A kind of intrinsic safety type pressure break pipe pusher, is characterized in that: it is made up of bearing 1, column 2, suspension arrangement 3, pusher 4, push rod 5 etc.
Bearing 1 is made up of fixed support and motion bar, and the two can split, and during accumulating separately, during work, is assembled into one.
Column 2 is vertically inserted in the hole on bearing, and suspension arrangement can slide up and down along column; Column there are more than 2 rounds or 2 rows along 90 degree of directions, for adjusting the position of suspension arrangement, and are fixed with a straight pin.
Suspension arrangement 3 is made up of suspended bearer and rotating stand.Suspended bearer can move up and down along column, and to adapt to the pressure break boring of differing heights, rotating stand and propulsion plant are bound up, and rotate along the suspended axle on suspended bearer, to adapt to the pressure break hole with certain angle.
Pusher 4 is made up of parts such as air motor, leading screw, feed screw nut, antero posterior axis bearing, support, pressure break pipe push-and-pull seats, air motor utilize down-hole easily compressed air be power, driving leading screw rotates, feed screw nut moves along leading screw together with push-and-pull seat, and pressure break pipe is arranged on push-and-pull seat and moves simultaneously.
Push rod 5 by outer bar, interior bar, hold out against feed screw apparatus etc. and form.Interior bar can portion's slippage be also fixing within the outer tube, to adapt to the position of different length; Leading screw is fixed on interior bar, rotational lead screw, the length of adjustable push rod, and makes push rod with certain pressure fixing pusher.
Because this pressure break pipe pusher is mechanical structure, air motor drives without any electric equipment, therefore is essential safe type device.
Accompanying drawing explanation
Fig. 1 is the structural representation of essential safe type pressure break pipe pusher of the present invention.
In figure: 1 bearing, 2 columns, 3 suspension arrangements, 4 pushers, 5 push rods.
Detailed description of the invention
Intrinsic safety type pressure break pipe pusher of the present invention is used to comprise the following steps:
1, according to the field condition of bore position, bearing, column is laid.Make base basic horizontal, column is substantially vertical.According to height and the angle of boring, height, the inclined degree of adjustment suspension arrangement, ensure that the center of the pressure break pipe be placed on push-and-pull seat overlaps substantially with drill center.
2, at the two ends of suspension arrangement, place two cover push rods, the length of adjustment push rod, makes them hold out against tunnel sidewall respectively, makes pusher fixing reliable.
3, connect gas path device, check whether blast reaches requirement, and first dry run stroke, whether checking device work is reliable.
4, after having checked, place pressure break pipe on bearing, actuating valve, makes motor driving screw turns, promotes push-and-pull seat and moves forward, pressure break pipe is sent in hole.Close gas check valve when nut moves to leading screw end, feed screw nut stops mobile, and pressure break pipe is separated with bearing, reverse opening air valve makes motor driving leading screw reversely rotate, drive feed screw nut and bearing to get back to origin-location again, since then, complete a working cycles.
5, after propelling movement terminates, push rod and suspension arrangement can be unclamped, make pusher drop to ground, wait for and continue to use.
6, after pressure break terminates, adjust pusher, by contrary operating sequence, successively the pull-out from boring of pressure break pipe, fracture job can be completed.
